+9 -6 =185 says only that both engine strength are close (within +-20 elo) next 200 games can be +10 -1 or -1 +10 specially crafted microbook (100 posiitions) can favour any desired contender.

Re: Stockfish performing bad on ryzen cpu.

There is no way Sf 12 should be getting only 1.5 mnps on 6 cores. this is expected speed for NNUE @ Qualcomm Snapdragon 855 Level 3 seconds/move, ponder on with Ponder=On and manual move enter - no one knows how much time actually each side get.

Re: Stockfish performing bad on ryzen cpu.

Different compiles will give NPS variation in order of percents, which will give few ELO variation in strength. Here we discuss enormous (in order of 200+ ELO) penalty, no matter which version was run on mobile. I still do not understand how exactly tournament is run. It is 0'+3" STC, run manually b...
